Just started our ds on yogurt one week ago and he was 8 months yesterday. Are going to wait a little on cheese but have heard the same as others - hard cheeses (grated is good to start), cream cheese and those little baby bels are good ones to use. Also, cottage cheese (great source of protien and a good finger food). Found a very good brand of baby yogurt in Canada by Dairyland that is available at Safeway and Walmart. There are 8 cups, two of each vanilla, banana, apple and peach for about $4.50 and there is no sugar added, sweetened with fruit juice and fruit puree and made with whole milk. Not organic, which is my preference but one of the better yogurt options I've come across for my lo!
